You mean some kind of indexing feature? Hmm . . . could be tricky to implement indexing into in_cdda.dll (assuming we're talking about Audio CD's here, and not mp3 data cd's?).
There might be a 3rd-party plugin, but I'm not personally aware of one.
The nearest you'll get at the mo is to use the Jump-to-time function (Ctrl+J)
but this means you'll need to know the exact starting points of each track.
It also depends on your cd burning software's functions.
I think Nero has an indexing feature (hey, I've got Nero5, but I've never actually needed to use such a feature, so I ain't rightly sure).
But you might be able to burn the track with indexing (so it treats each individual track in the mix as a separate file/track) and record/play them back in gapless mode . . . (like a gapless mix cd)
Anyone else got any ideas/suggestions? (actual "facts" welcome)
